Luca, your pointers were 100% on target! It took a few other things around that but the issue seems to be fixed now.
If you look at the code, you can see that this functionality could theoretically also be useful for line-breaking. Especially when we have side floats some day this could be very useful to avoid text to overflow into the side-flow. Even today, there are some constellations where this behaviour would make sense. But I think we'd need some additional code to handle every situation properly. For the moment, I've disabled the "part overflow recovery" (for lack of a better description) for line breaking. I've also disabled it for side region layout and block-containers since we want the overflow in these areas. Parts n > 0 will just be dropped anyway. Thanks for your help.
